Hi team,
customer tested the start up of tpsm82903 and found there is a significant glitch before start up. Vin=7V, Vout=0.9V,Iout=0.5A.
May I know the reason and how to eliminate this glitch? Thanks!

Hi Rayna,
I guess this was caused by small inductor and small output cap. The first pulse would charge the COUT and make VOUT a significant glitch.
Could you share the schematic here for further check?
Thanks,
Colin
